I have had this vase for some time. It is labelled as shown in Photo 1. No number. It is very atypical for a Kosta vase - buit it is not at all Murano-like either so I think the scatch marking is probably valid. Can anyone help with the range name and the approximate date. It is unlikely to be a one-off since I would expect a 'Unik" to be on the base if that were so.
